Abstract
The utility model relates to a vehicle rear suspension structure. The rear suspension is connected at the rear part of a vehicle frame, and connecting seats are respectively arranged at the rear part of the vehicle frame and on a rear axle bearing seat tube. The rear suspension comprises an arc-shaped lower rocking arm, left and right upper rocking arm levers, left and right shock absorbers and a rear axle bearing seat tube; the arc-shaped lower rocking arm is connected with the rear part of the vehicle frame through a single-point spherical joint, and the arc-shaped lower rocking arm is connected with the rear axle bearing seat tube through a double-point spherical joint; both ends of the left and the right upper rocking arm levers are respectively connected with the rear part of the vehicle frame and the spherical joints of the rear axle bearing seat tube; both ends of the left and the right shock absorbers are respectively connected with the rear part of the vehicle frame and the rear axle bearing seat tube. The vehicle rear suspension structure has the advantages that when the heights at which the two rear wheels are positioned are not identical, the spherical joints can be automatically adjusted according to the situation of the road surface, so that the vehicle body can maintain smooth, thereby the comfort level and the security of the vehicle are enhanced.
Description
Technical field
The utility model relates to a kind of rear suspension structure that is used on the power actuated vehicles such as four-wheel motor cycle, kart, farmer's car, beach buggy, Caddy.
Background technology
At present, rear suspension or be the dependent suspension structure of single trailing arm form on the power actuated vehicle on the market, or be independent suspension structure.The former wheel is not good enough to ground-surface ground connection property, just proposed a kind of " vehicle rear suspension structure " for No. 200620111430.1 as Chinese patent.In this technical scheme, vehicle frame is connected with the pull bar of chain stay by the right and left, the left and right pull bar Connection Block that respectively is provided with in vehicle frame rear portion, correspondence respectively is provided with cooresponding pull bar Connection Block in the chain stay front portion, shock-absorbing sleeve is loaded onto at chain stay pull bar two ends respectively, be fitted in respectively again in the pull bar Connection Block of vehicle frame and chain stay, by bolted.Correspondence position middle at the vehicle frame rear portion and with the chain stay front portion is respectively arranged with the cushion compound Connection Block, and cushion compound is fitted in any a connecting seat, by bolt two cushion compound Connection Blocks is tightened together.The connection structure of technique scheme can make vibrations that chain stay is delivered to vehicle frame through buffering repeatedly, and actv. reduces vibrations, increases the traveling comfort of taking.But because the chain stay pull bar two ends of said structure are fitted in respectively in the pull bar Connection Block of vehicle frame and chain stay, by bolted.This kind structure applications is when vehicles such as kart, beach buggy, and vehicles such as kart, beach buggy are often travelled on rough road and parked.When two trailing wheels height of living in was inconsistent, the chain stay structure that connects to ground in above-mentioned back can not be adjusted according to the road surface situation, and vehicle body just can tilt, and makes that the traveling comfort of vehicle and safety are undesirable.Independent suspension structure can effectively improve the traveling comfort of vehicle, but the transmission system complexity has increased cost.
Summary of the invention
The purpose of this utility model is: a kind of simple in structure, vehicle rear suspension structure that can reduce body inclination is provided.
The utility model is achieved through the following technical solutions:
A kind of vehicle rear suspension structure, rear suspension is connected in the vehicle frame rear portion, is respectively equipped with Connection Block on vehicle frame rear portion and the back axle bearing holder tube; It is characterized in that: described rear suspension comprises: arc lower shake-changing arm, left and right sides upper rocker arm bar, left and right sides shock absorber, back axle bearing holder tube; Arc lower shake-changing arm is connected for the single-point spherical joint with the vehicle frame rear portion, and arc lower shake-changing arm is connected for the two point spherical joint with the back axle bearing holder tube; Upper rocker arm bar two ends, the left and right sides are connected with back axle bearing holder tube spherical joint with the vehicle frame rear portion respectively; Shock absorber two ends, the left and right sides are connected with the back axle bearing holder tube with the vehicle frame rear portion respectively.
Advantage of the present utility model is: because arc lower shake-changing arm is connected for the single-point spherical joint with the vehicle frame rear portion, arc lower shake-changing arm is connected for the two point spherical joint with the back axle bearing holder tube; Upper rocker arm bar two ends, the left and right sides are connected with back axle bearing holder tube spherical joint with the vehicle frame rear portion respectively; When two trailing wheels height of living in was inconsistent, spherical joint can reduce body inclination according to road surface situation automatic compensation, makes the vehicle body held stationary, thereby has improved the traveling comfort and the safety of vehicle.Simultaneously, it is simple in structure, easily manufactured, cost is low with respect to independent suspension structure for vehicle rear suspension structure of the present utility model.Above-mentioned vehicle rear suspension structure is particularly suitable for using on the vehicles through travelling on the rough road of being everlasting such as kart, beach buggy.
In the utility model, described spherical joint is an oscillating bearing.
In the utility model, described oscillating bearing comprises: bearing carrier ring and the bulb of being located in the bearing carrier ring, the bulb middle part is provided with the perforate that is used to insert connecting pin.
In the utility model, shock absorber two ends, the described left and right sides are respectively equipped with the yielding rubber of band arc surface.The shock absorber two ends are connected with the back axle bearing holder tube with vehicle frame with the rubber buffering of band arc surface respectively.But has universal adaptation function in its small angle range, to adapt to the swing of rear suspension.
