Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of macpherson suspension structure, especially relates to a macpherson suspension on a flat head micro face car. BACKGROUND

[0002] The macpherson suspension is generally composed of a coil spring, a shock absorber, a lower swing arm, a steering knuckle, a subframe and a roll bar. Although the suspension has some deficiencies in roll resistance and braking, it is one of the most common independent suspension forms in modern vehicles because of its good controllability, compact structure, light weight, low cost and small space occupation, and its shortcomings can be overcome by proper adjustment and improvement to meet the needs of most vehicle models.

[0003] The micro face car is a small passenger and cargo dual-purpose car, mainly including convex head micro face and flat head micro face, wherein the configuration of the flat head micro face is simpler than that of the convex head micro face, and because the front space is limited, the flat head micro face cannot use the macpherson suspension like the convex head micro face, so the suspension structure of the flat head micro face is generally a double wishbone suspension structure or a leaf spring suspension structure.

[0004] The double wishbone suspension structure has high manufacturing cost and complex maintenance, and consumers who choose flat head micro face cars generally have limited budget, so flat micro face cars with double wishbone suspension structure are not popular among consumers. The leaf spring suspension structure is too heavy, and for flat head micro face cars with small displacement and the need to transport goods, this suspension structure also seriously reduces the market competitiveness of the flat head micro face car. UTILITY MODEL CONTENTS

[0005] In view of the above-mentioned shortcomings of the prior art, the utility model aims to provide a macpherson suspension on a flat head micro face car to solve the problem that the flat head micro face car cannot use the macpherson suspension like the convex head micro face car.

[0006] To achieve the above-mentioned purposes and other related purposes, the utility model provides a macpherson suspension on a flat head micro face car, which is installed below the front seat of the flat head micro face car, and comprises: a subframe for connecting various scattered suspension elements; two lower swing arms installed at both ends of the subframe; two steering knuckles installed on the two lower swing arms; two shock absorbers installed on the two steering knuckles; two coil springs sleeved on the two shock absorbers to form a sliding column structure; the axis of the shock absorber and the axis of the coil spring are collinear, and the bottom end of the coil spring extends into the inner ring of the tire; and a stabilizer bar connected to the two lower swing arms at both ends.

[0007] Optionally, the shape of the subframe is "H".

[0008] Optionally, one end of the lower swing arm is installed on the sub-frame through a bushing, and the other end of the lower swing arm is connected through a ball head and a steering knuckle.

[0009] Optionally, the lower end of the shock absorber is fixedly connected to the steering knuckle.

[0010] Optionally, the two ends of the stabilizer bar are respectively connected to the two lower swing arms through two anti-roll bars.

[0011] As described above, the MacPherson suspension of the flat head micro car has at least the following beneficial effects:

[0012] The MacPherson suspension of the flat head micro car is designed to be installed below the front seat of the flat head micro car. Compared with the prior art design of arranging the MacPherson suspension at the front of the flat head micro car, the length of the front suspension of the vehicle is reduced. Without additional increase in the length of the front of the flat head micro car or reduction in the internal space, the MacPherson suspension can be installed on the flat head micro car. At the same time, through the design that the axis of the shock absorber and the axis of the coil spring are collinear and the bottom end of the coil spring extends into the inner ring of the tire, compared with the MacPherson suspension with eccentric spring design, it is ensured that when the MacPherson suspension is installed below the front seat, the height of the driver and passenger getting on the vehicle can be effectively reduced. The flat head micro car with the MacPherson suspension and the flat head micro car with other suspensions can have approximately the same internal space and chassis height.
