Abstract
The invention discloses a back-wheel unit of microvehicle, which comprises the following parts: front shaft pipe, front hub shaft on two ends and back axial flange, wherein the back shaft of back shaft pipe rack is loaded in the back shaft pipe through two bearings, which can rotate in the back shaft pipe; two bearings on each back shaft possess roller bearing with inner coil; the back shaft of back shaft pipe rack is solid shaft.
Description
Technical field
The present invention relates to a kind of car chassis system, specifically a kind of hind axle assembly of minicar.
Background technology
The wheel at minicar rear axle and two ends thereof is to link to each other with vehicle body by rear coil springs, rear shock absorber, Rear drag arm, back transverse bar.Back brake system assembly also is installed on the rear axle in addition.Rear coil springs and rear shock absorber work to support the impact of car load and buffering uneven road surface.Rear drag arm is given vehicle body with the force transmission between tire and ground.Back transverse bar guarantees the lateral stability of car load.In the prior art, these mechanisms all separate with hind axle assembly, they all just are connected as a single entity in fitting process by annexes such as bearing, supports, assembling is complicated like this, efficient is low, because rear axle adopts pipe to make, so the support of rear axle tube and bearing be easy to damage, and automobile reliability also descends thereupon.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, and a kind of mini vehicle rear axle unit is provided.
Design of the present invention is: a kind of mini vehicle rear axle unit, the rear-wheel hub axle and the back axial flange that comprise rear axle tube and two ends thereof, rear axle tube support rear axle all is to be contained in the rear axle tube of rear axle tube support by two bearings, and can in the rear axle tube of rear axle tube support, rotate, two bearings on the rear axle tube support rear axle of every limit all are the coro bearngs that has inner ring, and rear axle tube support rear axle is a solid axle.
Adopt solid suspension type rear axle tube support rear axle, and the coro bearng that adopts the band outer ring is as the link that reverses of the rear axle tube of rear axle tube support and rear axle, the rear axle tube of the outer ring of bearing and rear axle tube support is a flush fit like this, the rear axle tube of rear axle tube support itself no longer bears the wearing and tearing that rolling brings of reversing of bearing, improved the intensity of the rear axle tube of rear axle tube support, and the rear axle of rear axle tube support adopts solid stepped shaft, has therefore also improved the stability of coro bearng and the strength and stiffness of rear axle itself.
Be connected with Rear drag arm bearing, rear coil springs seat, rear shock absorber seat, ABS wire harness bracket, brake pipe support, back transverse bar supporting pin on the described rear axle tube; And in rear axle tube, be provided with and strengthen rear-wheel hub axle and the back axial flange that bushing pipe minicar rear axle mainly comprises rear axle tube and two ends thereof.
Annexes such as the required bearing of the corresponding mechanism of the present invention's integrated body contact on rear axle tube, support, specifically exactly rear coil springs seat, rear shock absorber seat, Rear drag arm bearing, ABS wire harness bracket, brake pipe support, rear cross member lever pin etc. are fixed on the relevant position of rear axle tube, and in rear axle tube, be provided with reinforcement bushing pipe (9), make it to form one.
This hind axle assembly adopts punching press body and tubing to be welded light weight, intensity height.On rear axle tube, according to the stressing conditions at each position, weak part is provided with the reinforcement bushing pipe, guarantee the intensity of rear axle head factory.In addition, rear suspension, back brake system assembly etc. can be directly installed on the rear axle, and the latter half of assembling in car load chassis is simplified, and the efficiency of assembling height has also improved automobile reliability.Simultaneously, the durability that the back axle assembly gun barrel is hung in distortion obviously improves, and plays the width of cloth raising service life through testing.
Description of drawings
Figure 1 shows that structural representation of the present invention, Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
In conjunction with the accompanying drawings 1,2, non-limiting examples is described below.
Get tubing processing rear axle tube 5, in its two ends processing rear-wheel hub axle 1 and back axial flange 2.According to designing requirement, processed the bushing pipe 9 of booster action at the corresponding site of rear axle tube 5.On rear axle tube 5, weld Rear drag arm bearing 3, rear coil springs seat 4, rear shock absorber seat 6, ABS wire harness bracket 7, brake pipe support 8 and back transverse bar supporting pin at last.
The present invention adopts solid suspension type rear axle tube support rear axle, and the coro bearng that adopts the band outer ring is as the link that reverses of the rear axle tube of rear axle tube support and rear axle, the rear axle tube of the outer ring of bearing and rear axle tube support is a flush fit like this, the rear axle tube of rear axle tube support itself no longer bears the wearing and tearing that rolling brings of reversing of bearing, improved the intensity of the rear axle tube of rear axle tube support, and the rear axle of rear axle tube support adopts solid stepped shaft, has therefore also improved the stability of coro bearng and the strength and stiffness of rear axle itself.
After having adopted the present invention, the durability that the back axle assembly gun barrel is hung in distortion obviously improves, and can improve more than 2 times service life through test.
