Abstract
The utility model aims at providing a semi-axis structure based on stopper is stopped to dish makes stopper and semi-axis of stopping of dish can unite two into one, cancels semi-axis and the connection of the interior external splines of stopper is stopped to the dish to reduce the whole incremental cost of rear axle that causes because of the interior external splines of processing stopper and semi-axis, and reduce because of the probability that the quality problems that the internal and external splines assembly precision is difficult to guarantee to cause appear.
Description
Technical Field
The utility model relates to an electric automobile technical field, concretely relates to semi-axis structure based on dish stopper of stopping.
Background
The rear axle of the electric automobile is a main driving part of the electric automobile, and transmits power to rear wheels through a driving motor and a speed reducer. The half shaft in the rear axle is a solid shaft for transmitting torque between the differential and the driving wheel, the inner end of the half shaft is generally connected with the half shaft gear through splines, and the outer end of the half shaft is connected with the brake or the wheel hub. Present pure electric automobile dish is stopped and is driven rear axle, and dish stopper and semi-axis are individual alone generally, are in the same place through the spline assembly link, but because inside and outside spline processing is comparatively complicated, and the processing cost is higher, can cause the increase of bridge overall cost, and because the assembly precision is difficult to guarantee, can cause the increase of rear axle quality problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a semi-axis structure based on stopper is stopped to dish makes stopper and semi-axis of stopping of dish can unite two into one, cancels semi-axis and the connection of the interior external splines of stopper is stopped to the dish to reduce the whole incremental cost of rear axle that causes because of the interior external splines of processing stopper and semi-axis, and reduce because of the probability that the quality problems that the internal and external splines assembly precision is difficult to guarantee to cause appear.
In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a semi-axis structure based on dish stopper of stopping, includes wheel bolt (1), semi-axis flange (2), brake disc (3), bolt (4), braking wheel cylinder (5), bolt (6), goat's horn (7), bearing (8), bearing spacer (9), bearing (10), bolt (11), fender (12), semi-axis main part (13), oil blanket platform (14), spline (15).
The utility model adopts the integrated structure of the disc brake and the half shaft, so that the disc brake device is directly assembled on the half shaft, the spline connection between the disc brake device and the half shaft is cancelled, the integral cost of the rear axle is reduced, and the probability of the occurrence of quality problems is reduced; the bolt (1) and the half shaft flange (2) are assembled together in a press-fitting mode; the brake disc (3) and the half shaft flange (2) are assembled together through bolts (4); the brake cylinder (5) is assembled on the claw (7) through a bolt (6); a bearing (8) and a bearing (10) are arranged in the claw (7), the two bearings are separated by a bearing spacer sleeve (9), the inner rings of the two bearings are directly arranged on the half shaft main body (13), and the outer rings of the two bearings are contacted with the claw (7). (ii) a The mudguard (12) and the claw (7) are assembled together through a bolt (11); the inner end of the half shaft main body (13) is provided with an oil seal platform (14) and a spline (15).
The utility model has the advantages and beneficial effects that: by adopting the structure, the disc brake and the half shaft can be combined into a whole, and the connection between the half shaft and the internal and external splines of the disc brake is cancelled, so that the cost of the whole rear axle increased due to the processing of the internal and external splines of the brake and the half shaft is reduced, and the probability of the quality problem caused by the difficulty in ensuring the assembling precision of the internal and external splines is reduced.
Drawings
The invention is described in detail below with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
