Hydraulic stepless speed change power wheel

Abstract

The invention relates to an automobile driving wheel, in particular to a hydraulic stepless speed change power wheel. The hydraulic stepless speed change power wheel comprises a slide rod and drivinghydraulic pushing mechanisms arranged at the two ends of the sliding rod respectively; a driven hydraulic pushing mechanism is arranged on the sliding rod; and the sliding rod is connected with the outer contour of a hub through the driven hydraulic pushing mechanism. A plurality of sliding protrusions are arranged on the sliding rod in the circumferential direction of the sliding rod and arrangedin the axial direction of the sliding rod. The driven hydraulic pushing mechanism comprises central driven hydraulic housings and a central driven hydraulic push rod; the plurality of center driven hydraulic housings are arranged in the circumferential direction of the push rod at intervals; the center driven hydraulic housings are arranged in the radial direction of the push rod and connected with the push rod in a sliding mode; the adjacent center driven hydraulic housings are fixedly connected through connecting rods; and one ends of the center driven hydraulic push rods are arranged in the center driven hydraulic housings, and the other ends of the center driven hydraulic push rods are fixedly connected with the outer contour. The hydraulic stepless speed change power wheel is simplein structure, convenient to use, small in occupied space and not prone to being affected by external pressure.

Description

technical field [0001] The invention relates to an automobile drive wheel, in particular to a hydraulic continuously variable speed power wheel. Background technique [0002] In the development of automobiles, gearboxes, as the core part of automobiles, have been researched and improved all the time, among which the continuously variable transmission of automobiles is an important development direction. In the prior art, manual gearboxes and automatic gearboxes have complex structures, and most of them use gear combination shifting. When this shifting method has more shifting gears, there will be more parts in the gearbox. Generally, it is increased to 7 gears. In the end, the number of parts will exceed 500, which poses great challenges to technology and cost, and it is generally difficult to continue to increase the number of gears. In addition, the relatively mature steel belt continuously variable transmission technology uses steel belt for friction transmission, which ...

Problems solved by technology

In the prior art, manual gearboxes and automatic gearboxes have complex structures, and most of them use gear combination shifting. In this shifting method, the more gears there are, the more parts will be in the gearbox. Generally, it is increased to 7 gears. In the end, the number of parts will exceed 500, which poses great challenges to technology and cost, and it is generally difficult to continue to increase the number of gears

In addition, the relatively mature steel belt continuously variable transmission technology uses steel belt for friction transmission, which is different from the transmission gear transmission. However, the steel belt continuously variable transmission technology is limited by the material properties and friction of the steel belt, so it cannot be applied in large power car
