Problems solved by technology

However, it was found during use that the spring support plate of the independent suspension device was installed obliquely along the direction of the waist frame during production. In the point contact state, the fatigue resistance of the spring will deteriorate after long-term use, resulting in the deterioration of the overall shock absorption effect of the vehicle; the second is that the hinge point between the spring support plate and the damping rod is too low, which affects the overall height of the vehicle chassis. Constraints, vehicles create obstacles when passing over bumpy roads

Embodiment Construction

[0009] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0010] combined with figure 1 and attached figure 2 As shown in the figure, the wheel system independent suspension device of the trailer-type house includes a waist frame 2 which is hingedly fixed to the frame 1 and is inclined to the bottom of the frame. The wheel shaft mounting plate 3 is fixed on the waist frame, and the front end of the waist frame has a spring support plate. 4. One end of the damping rod 5 is hinged to the spring support plate, and the other end is hinged to the frame body, and a shock absorbing spring 6 is arranged between the spring support plate and the frame body.

[0011] as attached figure 1 As shown, there are two sets of independent suspension devices for the wheel system, which are symmetrically distributed on both sides of the bottom of the frame. In order to increase the strength and shock absorption effect, there ar...

Abstract

The invention belongs to the technical field of vehicle manufacturing. In order to solve the technical problems existing in a conventional independent suspension device for a wheel system of a travel trailer that hinge points are too low, and a damping spring is easy to lose elasticity, the invention provides an independent suspension device for a wheel system of a travel trailer. The independent suspension device comprises a waist rack which is fixed to a vehicle rack in a hinged manner and tilts towards the bottom of the vehicle rack, wherein a wheel-axle mounting disc is fixed on the waist rack; a spring supporting disc is arranged at the front end of the waist rack; one ends of damping vibration attenuation rods are hinged to the spring supporting disc, and the other ends of the damping vibration attenuation rods are hinged to the rack body of the vehicle rack; a vibration attenuation spring is arranged between the spring supporting disc and the rack body of the vehicle rack. The independent suspension device is characterized in that a folded angle is formed between the spring supporting disc and the connected end of the waist rack, and the spring supporting disc is positioned in the horizontal state. The independent suspension device for the wheel system of the travel trailer is simple in structure and convenient to transform, and can be widely applied in the manufacturing of vehicles.

Description

technical field [0001] The invention belongs to the technical field of vehicle manufacturing, and in particular relates to an independent suspension device for a wheel system of a trailer type house. Background technique [0002] Since the trailer-type caravan has no independent driving force, its two wheels are respectively fixed on the independent suspension device at the bottom of the frame through the wheel axle, and the structure is as follows: figure 1 As shown, it includes a waist frame that is hinged and fixed to the frame and is inclined to the bottom of the frame. The wheel axle mounting plate is fixed on the waist frame. The front end of the waist frame has a spring support plate, and one end of the damping rod is hinged to the spring support plate. , the other end is hinged with the vehicle frame body, and a damping spring is arranged between the spring support plate and the vehicle frame body. The waist frame and damping rod form a "√" type independent suspensi...
