A bridge, especially a host, is a complex node with many details that perform different functions. The leading bridge in the crankcase is the main pair, the differential and the semi-axis. The bridge takes on all vertical, lateral and longitudinal loads that are extinguated by the elastic elements of the suspension or springs.
Accordingly, the bridge does not have a rigid relationship to the body (frame) and is connected to it by means of a jet rod or spring levers, depending on the structure. In essence, the bridge is hung on these elements connected to the body or frame through rubber metal tuples.
Types of road bridges
- Moderators
- Managed
- Managed Moderators
- Supporting
Leading bridges are the front, the rear and the intermediate. They are also divided into uncarved and rivelled-depending on the type of suspension. If the car is equipped with an independent suspension, the bridge is riven if the suspension is dependent and the bridge is usually not carved.
For passenger cars of classic build rear axle bridge leading, four-wheel-drive cars leading both bridges.
Managed bridge
When it comes to a controlled bridge, in the vast majority of cases the front of the vehicle is referred to as a rear-wheel or full-drive vehicle. However, for special purpose vehicles (utility vehicles, agricultural wheeled vehicles, forklift trucks), the front bridge can be the driving bridge and the rear bridge can be managed.
Supporting bridge
The supporting bridge is used as an intermediate to increase the load capacity of the vehicle and serves as an additional element in the vertical load distribution scheme for the rama or the carrying body. The bridge is a forward beam, at the end of which the wheels fitted with suspension are mounted. The supporting bridges have also been used in large and heavy semi-trailers and trailers for cars and pickups (e.g. in a "home on wheels").
The Undivided Host Bridge
This bridge is structurally empty in the form of a beam, for the placement of transmission points in it: the differential, the main pair and the half-axles leading to the driving wheels of the car. At the ends of the beam, the bearings of the semiaxles have been installed and flanges for securing the support disks and braking mechanisms have been installed. The body of the beam is satisfied with the ground of the attachment or springs, as well as the brackets for connecting to the suspension.
The purpose of the lead bridge is to modify the tortorques and to transmit it at right angles to the driving wheels. During rotation, the driving bridge allows the driving wheels of the vehicle to rotate at different speeds. The bridge also transmits the traction force and the jet to the chassis or body of the car from the driving wheels, and also takes the strength of the weight and lateral reactions when the vehicle is moving in turn.
Rear-bridge non-carrion design
The rear axle bridge consists of the following elements: rear axle crankcase, differential, main gear and half wheel drive. The rear bridge Carter is used to install the necessary nodes with their given torque to the driving wheels. At the same time, the rear axle crater is at the same time the rear wheel suspension elements, which resigns by the weight of the vehicle on the wheel.
The carter of the rear bridge was done by stamping. At the end of the crankcase, the steel wrought iron flanges are shut and welded in welded. The flanges have special sockets to install the bearings and threads for the attachment of the brake shield.
On the middle part of the bridge crankcase there is an opening in front to install the rear axle reductor (main gear), and the rear of the opening is closed by a weld bolted lid. There is a filler hole under the threaded plug. The crankcase has an opening for discharge of oil, which is also covered by the threaded plug. Usually there is a magnetic element in the cork to collect metal products of wear that are removed from the cork when the oil is changed in the gearbox.
The torque output (torque) from the engine through the card shall be increased by the main gear in the gear box. In addition, the main gear changes the position of the axis of rotation 90 degrees by passing the moment through the six-axis differential.
The semi-axles have been made of carbon steel 40 and have been tempered by THF to give them resilient properties and increase their strength. At the ends of the semi-axes, the flanges with which the braking mechanisms and wheels are attached shall be present. The interior part of the semi-axis has an inflated slit of clinging to the gears of the gears of the gears.
Managed bridge
The managed bridge of the car can be both rifled and non-carved.
The non-rivelled bridge is a rake at the end, which provides the ability to steer the steering wheels when driving. At the clapps of the swivel, the steering pits shall be secured through the steering wheels.
The bridge of the bridge shall at the same time be light, strong and rigid. These conditions are most likely to be met by the shackled steel beams of the bivy section. The beam provides support sites for fixing the suspension elements.
The lower part of the belk is bent down to position the engine as low as possible, which allows the centre of gravity to be removed to make the vehicle more sustainable.
Adjacent managed bridge
The carved bridge is a retractor with a wheel torque reducer attached to the wheels. The independent suspension is connected to the turning-fists, as is the way of the front-wheel-drive cars. The steered wheels attached to the steps may be rotated with the frames, providing the vehicle with the ability to manoeuvre.
