This invention relates to the field of motorsports technology, and more particularly to a transmission system for an off-road rally car and a race car equipped with the transmission system. The system includes a frame and a transmission system mounted on the frame. Wheels are mounted on the frame via a suspension system. The transmission system includes a gearbox mounted at the rear of the frame and a differential mounted at the front of the frame; the gearbox and the differential are connected by a first driveshaft positioned at the front and rear. The suspension system includes front steering knuckles located inside the two front wheels, both of which are fixed to the front side of the frame via upper and lower double wishbone suspensions. This off-road rally car has advantages such as lighter weight, more compact structure, better handling, superior passability, and higher safety. The lighter vehicle has sufficient power performance, and its low self-friction resistance during travel improves its ability to traverse uneven roads, reducing the risk of rollover and thus improving race performance.

The application discloses a spring-over double wishbone suspension structure based on a corner module, which comprises a steering knuckle connected with a wheel hub on one side; a connecting corner matched with the steering knuckle, the steering knuckle and the connecting corner having coaxial through holes; a driving mechanism, an output end of which is provided with an angular contact bearing, the Z-direction freedom of the angular contact bearing being limited through the steering knuckle and the connecting corner; an air spring installed above the connecting corner; an upper cross arm arranged in the middle of the connecting corner; and a lower cross arm connected with the steering knuckle through a ball hinge. The air spring is arranged above, and the angular contact bearing is designed, so that the stress of the spring can be effectively shared, the stability and responsiveness of the suspension system are improved, the impact caused by the uneven road surface can be more efficiently absorbed, especially when steering and emergency braking, the suspension system can show better control ability, the body roll and shaking are reduced, and the vehicle is more stable and stable when running at high speed and in complex road conditions.

This invention relates to an active wheel camber adjustment suspension system based on double wishbone suspension and a vehicle, comprising: a mounting bracket; at least one wheel unit including a wheel and a steering component, the steering component being mounted on the wheel and having a first mounting position and a second mounting position; at least one wishbone unit including a first wishbone and a second wishbone, one end of the second wishbone being movably connected to the second mounting position and the other end of the second wishbone being movably connected to the mounting bracket; and at least one adjustment unit including an adjustment drive component and an adjustment control component, the adjustment control component controlling the movement of the adjustment drive component, one end of the first wishbone being movably connected to the first mounting position. This invention can actively adjust the wheel camber angle in real time according to the vehicle's driving state, thereby reducing tire wear during straight-line driving, increasing the tire contact area during cornering, significantly improving the vehicle's cornering limit handling performance, reducing tire wear, and extending tire life.

The utility model provides a kind of fixed support and shock absorber indicator, it relates to automobile parts test equipment technical field, and wherein, fixed support mainly includes first support, second support and locking part. First support is provided with first through-hole;Second support is provided with second through-hole, and first support and second support are used to be fixedly connected with double wishbone suspension;First through-hole and second through-hole correspond, and at least one of first through-hole and second through-hole is long strip-shaped adjusting hole, and at least one of first support and second support moves along the length direction of adjusting hole, so that first support and second support relatively close or move away;Locking part is arranged in first support and second support by first through-hole and second through-hole, so that first support and second support are locked or unlocked. Through the embodiment provided in the present application, the double wishbone suspension of different span is adapted, and the problem that shock absorber indicator cannot test double wishbone suspension is effectively solved.

This utility model discloses a lower control arm for a double wishbone suspension in passenger vehicles, relating to the field of automotive suspension. It includes a control arm body with three arms and a ball joint assembly. The control arm body includes a first sheet metal part and a second sheet metal part, with the second sheet metal part mounted on the first sheet metal part and connected at its edge. A hollow buffer chamber is provided between the first and second sheet metal parts. The ball joint assembly includes a pin seat and a ball pin, with the pin seat partially inserted into the buffer chamber and detachably connected to the first arm of the control arm body. The ball pin is riveted and press-fitted into the pin seat. By mounting the second sheet metal part on the first sheet metal part and connecting it at its edge, and by providing a hollow buffer chamber between the first and second sheet metal parts, the sheet metal design is less expensive than forged or cast parts. The hollow buffer chamber allows the lower control arm to deform and absorb collision loads, preventing axle breakage and loss of driving function, and also reducing the weight of the device.

This utility model discloses a high-performance double wishbone suspension shock absorber, relating to the field of vibration reduction technology, including a damper and an electromagnetic component. The electromagnetic component includes a mounting member, the bottom of which is fixedly connected to the top of the damper. A first extension plate is fixedly connected to the side surface of the mounting member, and a sliding sleeve is fixedly connected to the bottom of the first extension plate. A permanent magnet is slidably connected to the inner wall of the sliding sleeve, and an extension rod is fixedly connected to the bottom of the permanent magnet. This high-performance double wishbone suspension shock absorber, when the telescopic end of the shock absorber in the damper moves, induces a current through the movement of the permanent magnet within the coil. Depending on the requirements, this current can be used to power a battery, improving range performance, or the coil can be directly connected end-to-end to generate eddy currents while producing the induced current, thereby generating damping and increasing the damping coefficient, thus improving vibration reduction performance.
