Description
Technical Field
The utility model relates to a vehicle field especially relates to a pile driver rear axle and this pile driver.
Background
The pile machine that is common in the existing market, rear wheel drive all adopt the transmission structural style of axle plus sprocket chain basically, the biggest drawback of this structure is in that whole car can't form differential drive when the operation of going, leads to forming sliding friction between tire and the ground, greatly increased the consumption and the wearing and tearing of tire, reduced work efficiency, tire maintenance and cost of maintenance also increase thereupon, to the road engineering equipment machinery that operational environment is complicated, the transition wearing and tearing of tire are the fatal shortcoming undoubtedly, are unfavorable for the long-term development of this product.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a pile driver rear axle and this pile driver, the utility model discloses a rear axle drive structure of gearbox makes tire and ground form the differential transmission when putting in order the car operation of traveling between, changes sliding friction into pure rolling friction, greatly reduced the loss between tire and ground, improved the life of tire.
The technical scheme of the utility model is specifically as follows:
the utility model provides a pile driver rear axle, includes bevel gear differential mechanism, and bevel gear differential mechanism's driven gear is connected with first output semi-axis, and output semi-axis gear passes through the differential lock unit to be connected with second output semi-axis.
Further, the driving gear of the bevel gear differential is connected with the power input shaft.
Furthermore, the differential lock unit comprises a first differential lock gear sleeve, the first differential lock gear sleeve is fixedly connected with the differential shell, the first differential lock gear sleeve is sleeved on the second output half shaft, the second differential lock gear sleeve is matched with the second output half shaft through internal and external splines, and the second differential lock gear sleeve moves left and right through a differential lock shifting fork to be meshed with the first differential lock gear sleeve, so that the differential is controlled.
Further, a first output half shaft is connected with the first drive wheel and a second output half shaft is connected with the second drive wheel.
Furthermore, the bevel gear differential, the first output half shaft, the second output half shaft and the differential lock unit are arranged in the rear axle protective shell, and one end of a differential lock shifting fork of the differential lock unit extends out of the rear axle protective shell.
Further, the upper sides of the two ends of the protective shell are provided with mounting plates.
The utility model discloses a pile driver still relates to, including foretell rear axle.
The utility model discloses well differential mechanism's effect is when transmitting power to both sides semi-axis, allows the rotation of both sides semi-axis with the rotational speed of difference, satisfies both sides wheel and does not equidistance travel with pure rolling form as far as, reduces the friction of tire and ground. Mainly is embodied in that when the whole vehicle turns, the left wheel and the right wheel rotate in a differential way, the turning radius is reduced, and the abrasion between the tire and the ground is reduced.
Compared with the prior art, the beneficial effects of the utility model are as follows:
the utility model discloses a take differential mechanism's gearbox rear axle structure, stake machine are when traveling, and application differential mechanism advances the transmission of power to the semi-axis on both sides, and meanwhile, the semi-axis on these both sides to different speed is rotatory, thereby satisfies the wheel on both sides and at the in-process of traveling, replaces traveling of distance that varies with pure rolling traveling. Therefore, the friction between the ground and the tire can be greatly reduced, the running resistance is reduced, the running speed is improved, the tire is protected to a certain degree, the tire is not easily abraded, and the replacement frequency of the tire is reduced. Furthermore, differential transmission is formed between the tire and the ground, the transmission ratio is adjusted, sliding friction is changed into pure rolling friction, loss between the tire and the ground is greatly reduced, and the service life of the tire is prolonged.
