Embodiment Construction

[0015] Embodiment of pure electric sanitation vehicle

[0016] This embodiment provides a pure electric sanitation vehicle, which includes a power system and, of course, other components. Since other components are not the focus of protection of the sanitation vehicle, no specific description will be given here.

[0017] like figure 1 As shown, the power system includes a motor 1, a motor 2, a gearbox 1, a gearbox 2, a power transmission shaft and an operating device, wherein, the gearbox 1 and the gearbox 2 both take an automatic gearbox as an example, and further, they are two-speed gearbox. The motor 1 is connected to one end of the automatic transmission 1 (ie, the input shaft of the automatic transmission 1), the motor 2 is a double-shaft motor, and the first power output end of the motor 2 is connected to one end of the automatic transmission 2 (ie, the input shaft of the automatic transmission 2). Input shaft), the other end of the automatic transmission 1 and the oth...

Abstract

The invention relates to a pure electric sanitation vehicle and a power system thereof. The power system comprises a first motor, a first gearbox, a second motor, a second gearbox, a power transmission shaft and a working device. The first motor and the second motor are separately connected with the power transmission shaft through the corresponding gearboxes, the first motor and the second motorcan output power separately or together, and the motors can achieve deceleration torque-increase or speed-increase torque-decrease through the corresponding gearboxes separately. The power system cansimultaneously meet the requirements of high-speed driving and high torque of the vehicle, and the working efficiency of the system is improved; furthermore, a motor with relatively large torque and relatively large output speed is not required, and the cost is reduced; and in addition, the single motor is selected for operation or the two motors are selected for operation at the same time according to different working conditions, it is guaranteed that the motors can work in the high-efficiency operation zone regardless of the working conditions, the motor operation efficiency is improved, the 'a big horse drive s little car' phenomenon is avoided, and vehicle energy consumption is reduced.

Description

technical field [0001] The invention relates to a pure electric sanitation vehicle and its power system. Background technique [0002] As the problem of environmental pollution becomes more and more serious, urban functional vehicles are gradually transforming into new energy vehicles. Since sanitation vehicles do not need a long working history and the particularity of working hours, pure electric sanitation vehicles can fully meet the normal work and driving requirements of sanitation vehicles. At present, the power system of pure electric sanitation vehicles mainly has the following problems: pure electric sanitation vehicles, especially garbage transport vehicles, are limited by road conditions when dumping garbage in garbage dumps, and sometimes require a large climbing ability, but when the vehicle is driving normally or in urban areas Such a large climbing ability is not used during operation. In order to solve the above problems, the Chinese patent document with the...
