Abstract
The utility model discloses a rear suspension system for a light automobile. The system comprises a stabilizer bar support connected to a longitudinal member, a sleeve connected to the stabilizer bar support, a rear transverse stabilizer bar horizontally arranged on the lower plane in the rear section of the automobile frame in the sleeve in a twisting manner and a stabilizer bar connecting rod assembly connected with the rear transverse stabilizer bar. The stabilizer bar connecting rod assembly is connected with a rear steel plate spring at the same time. According to characteristics of N1 type vehicles, the rear transverse stabilizer bar is fixedly arranged on the frame, and the other end of the stabilizer bar connecting rod assembly is fixedly arranged on the steel plate spring, so that the structure is simple, the space is saved and the steering stability of the vehicle is improved, therefore, the heeling hidden dangers of the vehicle steering are eliminated to the maximum extent, and the operability of the vehicle is improved.
Description
Technical field
The utility model belongs to rear-suspension system, is specifically related to a kind of lilliput car rear suspension system.
Background technology
At present, the rear-suspension system that the light truck-type of traditional N1 class adopts is the structure of steel spring+hydraulic damper, and N1 class vehicle refers to that maximum design total mass is no more than the goods carrying vehicle of 3500 kg.The hidden danger of quality that rolls when the higher vehicle of centers of gravity such as boxed truck can occur turning to, in order to address this problem, need in rear-suspension system, increase back Panhard rod assembly, thereby increase the stability of vehicle when turning to, the hidden danger that rolls when at utmost eliminating Vehicular turn has improved the handling of vehicle.
Panhard rod (sway bar, anti-roll bar, stabilizer bar) claims sway bar again, is a kind of assistant spring element in the automotive suspension.Its effect is to prevent that vehicle body from excessive horizontal inclination taking place when turning.Purpose is to prevent the automobile sideways overturning and improve ride comfort.Panhard rod is the torsion bar spring made from spring steel, and shape is " U " shape, horizontal front-end and back-end at automobile.The middle part of shaft, hinged with sleeve and vehicle frame, the two ends of bar are separately fixed on the suspension of the left and right sides.When vehicle body was only made perpendicular movement, suspension distortion in both sides was identical, and Panhard rod is inoperative.When body roll, the both sides suspension is beated inconsistent, and Panhard rod twists, and the elastic force of shaft becomes the resistance that continues inclination, plays laterally stable effect.
In order to adapt to N1 class vehicle, need be optimized Panhard rod, make its layout simpler, convenient.
The utility model content
The purpose of this utility model is at above-mentioned situation, and a kind of lilliput car rear suspension system of the N1 of adaptation class vehicle is provided.
The purpose of this utility model realizes by following technical proposals:
A kind of lilliput car rear suspension system, the stabilizer rod pipe link assembly that comprise the stabilizer rod supporting that is connected on the chassis side rail, be connected lining in the described stabilizer rod supporting, the back Panhard rod of the horizontal back segment lower plane at automobile chassis frame that twists in described lining is connected with the back Panhard rod, described stabilizer rod pipe link assembly connects rear leaf spring simultaneously.
As optimal way, described stabilizer rod supporting and described lining clamping.
As optimal way, described stabilizer rod supporting is provided with arc surface, the outside face interference fit of described arc surface and lining.
As optimal way, described lining is semi-circular for fluting, and the inside of lining is provided with diameter less than the mating holes of described back diameter of lateral, and the vertical surface of lining is provided with the horizontal joint that is communicated with mating holes.
As optimal way, described lining is rubber bush.
As optimal way, described stabilizer rod pipe link assembly is connected with the Z-shaped support of described rear leaf spring by bolt.
As optimal way, described stabilizer rod pipe link assembly comprises horizontal brace rod, vertical connecting, and is set on pad, rubber pad, flange nut on the described vertical connecting.
As optimal way, described horizontal brace rod pass the back on the Panhard rod connecting bore and by nut locking.
As optimal way, described back Panhard rod is U-shaped.
As optimal way, described stabilizer rod supporting is connected on the chassis side rail by bolt.
Vehicle body is when only for vertical movement and two sorrowful spring deflections equate when vehicle is kept straight on, and back Panhard rod freely rotates in rubber bush, and back Panhard rod is inoperative; When travelling when Vehicular turn or on rough road surface, the both sides spring deflection does not wait and makes vehicle body for road-bank elevation, the nearly steel spring of one sidesway of vehicle frame, this side of back Panhard rod is terminal just upwards moves with respect to vehicle frame, and the opposite side of vehicle frame is away from steel spring, so the back Panhard rod is just reversed.The moment of resistance of reversing that elastomeric back Panhard rod produces has just stoped the distortion of steel spring, thereby has reduced lateral inclination and the lateral angle vibration of vehicle body.
Useful technique effect of the present utility model is:
1, the utility model has increased the stability of vehicle when turning to, thereby the hidden danger that rolls when at utmost eliminating Vehicular turn has improved the handling of vehicle.
2, the utility model is fixed in the back Panhard rod on the vehicle frame according to the characteristics of N1 class vehicle, and the other end of stabilizer rod pipe link assembly is fixed on the steel spring, arranges simply and saved the space.
Description of drawings
Fig. 1 is exploded perspective view of the present utility model.
Wherein, 1 is rear leaf spring, and 2 is stabilizer rod pipe link assembly, and 3 is the back Panhard rod, and 4 are the stabilizer rod supporting, 5 is rubber bush, and 6 is horizontal joint, and 7 is horizontal brace rod, and 8 is vertical connecting, and 9 is pad, 10 is rubber pad, and 11 is the flange nut, and 12 is mating holes, and 13 is connecting bore.
The specific embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
As shown in the figure, a kind of lilliput car rear suspension system, the stabilizer rod pipe link assembly 2 that comprise the stabilizer rod supporting 4 that is connected on the chassis side rail, be connected lining 5 in the described stabilizer rod supporting 4, the back Panhard rod 3 of the horizontal back segment lower plane at automobile chassis frame that can freely twist described lining 5 in is connected with back Panhard rod 3, described stabilizer rod pipe link assembly 2 connects rear leaf spring 1 simultaneously.
