Problems solved by technology

The main defect of the chain transmission system is: the distance between the center shaft and the rear shaft is far away, the chain is long, the chain and the sprocket produce a lot of friction during the transmission process, and the best mechanical performance cannot be achieved, especially when The friction generated by the chain and sprockets increases non-linearly when the two sprockets are not in line
People need to overcome these frictional forces when riding a bicycle, even if the transmission efficiency of a bicycle using a chain transmission system is relatively low, the rider is very laborious, which restricts the application and popularization of bicycles.

Embodiment 1

[0009] Example 1: Front-drive

[0010] see figure 1 and 2 , said drive shaft refers to front axle 4, and said hydraulic transmission system is a closed-loop system composed of oil tank 10, hydraulic pump 14 and front hydraulic motor through front oil supply pipeline 8 and front oil return pipeline 7. A one-way valve 11 is arranged on the top; the central shaft 20 is used as the input shaft of the gear transmission 15, and the output shaft of the gear transmission is used as the input shaft of the hydraulic pump; the said hydraulic motor is the front hydraulic motor 6, which is installed near the front axle , the front chain drive system 5 is installed on the main shaft and the front axle of the front hydraulic motor, that is, the main shaft torque of the front hydraulic motor is transmitted to the front axle through the front chain drive system. When the rider steps on the pedal 1, the center shaft, the gear transmission and the hydraulic pump are driven to rotate in turn, a...

Embodiment 2

[0014] Embodiment 2: Rear drive type

[0015] The said drive shaft can also refer to the rear axle 17. Correspondingly, the said hydraulic transmission system is a closed-loop system composed of the oil tank 10, the hydraulic pump 14 and the rear hydraulic motor 16 through the rear oil supply pipeline 9 and the rear oil return pipeline. , the rear hydraulic motor is installed in the vicinity of the rear axle, and the rear chain transmission system 18 is installed on the main shaft and the rear axle of the rear hydraulic motor, that is, the main shaft torque of the rear hydraulic motor is delivered to the rear axle by the rear chain transmission system. Others are the same as in Embodiment 1.

Embodiment 3

[0016] Embodiment 3: Dual-drive type

[0017] It is a combination of Embodiments 1 and 2, specifically, the front circuit composed of the front oil supply pipeline, the front hydraulic motor and the front oil return pipeline, and the rear circuit composed of the rear oil supply pipeline, the rear hydraulic motor and the rear oil return pipeline, Connect in parallel at the oil outlet on the reversing valve. Others are the same as above.

Abstract

The invention provides a hydraulic transmission non-motor vehicle which solves problems that transmission efficiency of a chain transmission bicycle is lower, bicycling needs great strength, and application and population of a bicycle are restricted. The hydraulic transmission non-motor vehicle has key points that a hydraulic transmission system is a closed loop system formed by an oil tank, a hydraulic pump and a hydraulic motor through a pipeline; a middle shaft serves an input shaft of a gear speed changer, an output shaft of the gear speed changer serves as an input shaft of the hydraulic pump; and the hydraulic motor is arranged near a driving shaft, and chain transmission systems are arranged on a main shaft and the driving shaft of the hydraulic motor. The hydraulic transmission non-motor vehicle has positive effects that no friction is caused nearly as the main transmission system adopts the hydraulic transmission system instead of the chain transmission systems, so that friction can be greatly reduced.

Description

technical field [0001] The invention relates to a non-motor vehicle (including bicycles, tricycles, etc.), especially a non-motor vehicle with hydraulic transmission. Background technique [0002] In today's era of energy saving and environmental protection, bicycles are more and more valued by people. In order to encourage citizens to use bicycles to travel more, governments at all levels have also set up special bicycle lanes on public roads. The main transmission system of the current bicycle mainly adopts a chain transmission system, and the chain transmission system transmits the torque of the bicycle center shaft (ie, the output shaft of the pedal) to the drive shaft (generally the rear axle). The main defect of the chain transmission system is: the distance between the center shaft and the rear shaft is far away, the chain is long, the chain and the sprocket produce a lot of friction during the transmission process, and the best mechanical performance cannot be achie...
