Abstract
The utility model relates to a power semi-trailer electric vehicle chassis which mainly comprises a framework assembly, a front axle assembly, a rear axle assembly, a power assembly, a storage battery and a control system, wherein the motor output end is connected with the input end of the gearbox assembly, the output end of the gearbox assembly is connected with the input end of the rear axle assembly through a transmission shaft, and the power assembly is arranged to be a semi-trailer power assembly. In the semi-trailer power electric vehicle chassis provided by the utility model, the power assembly is arranged to be a U shape, and is positioned in the middle rear part of the chassis, so that the power transmission route is short, and the longitudinally occupied space is small. Therefore, the cross beam of the vehicle frame is complete, the middle of the framework assembly is flat, the height of the upper surface of the vehicle frame is reduced, and the rigidity of the vehicle frame and the convenience in boarding and alighting can be guaranteed; and meanwhile, the entire power transmission system is longitudinally arranged in parallel, and is more energy saving.
Description
Technical field
The utility model relates to a kind of battery-driven car chassis technology field, is in particular a kind of power semi-trailer battery-driven car chassis.
Background technology
The prior electric chassis generally is made up of six major parts such as frame assembly, front axle assy, back axle assembly, dynamic assembly, storage battery, control system in the market; Wherein be installed in the front and rear of frame assembly respectively at front axle assy, back axle assembly; Dynamic assembly is installed between two bridges; Be vertical straight-though arrangement, promptly the input end three of motor, transmission assembly, back axle assembly is on an axis basically.Motor output end is connected with the input end of transmission assembly; Gear box output end is connected with the back axle input end through transmission shaft; Above structure makes motor, transmission assembly and transmission shaft need vertical straight-though arrangement in the central frame beam position; Can have more a bulge longitudinally on the floor, cross member of frame becomes disconnected beam or ingot beam, and the plane is liftoff also bigger on the vehicle frame.Vehicle frame rigidity and HOP ON property are all received very big influence like this.Our a kind of power semi-trailer battery-driven car chassis of exploitation can solve these problems for this reason.
Summary of the invention
The technical matters that the utility model will solve is: overcome the shortcoming of above prior art, a kind of power semi-trailer battery-driven car chassis is provided.
The technical scheme that the utility model solves above technical matters is: a kind of power semi-trailer battery-driven car chassis; Mainly comprise frame assembly, front axle assy, back axle assembly, dynamic assembly, storage battery, control system; Said motor output end is connected with the input end of transmission assembly; The mouth of transmission assembly is connected with the back axle assembly input end through transmission shaft, and it is characterized in that: dynamic assembly is set to the semi-trailer dynamic assembly.
The purpose of the utility model can also further realize through following technological solution:
Aforesaid a kind of power semi-trailer battery-driven car chassis; Wherein said semi-trailer dynamic assembly is made up of motor, transmission assembly and " A " font propelling rod; Be vertically " U " type setting, and be positioned at the place ahead of back axle assembly, semi-trailer dynamic assembly one side hangs on the frame assembly; Opposite side hangs on the back axle assembly, forms the semi-trailer structure.
Aforesaid a kind of power semi-trailer battery-driven car chassis, wherein said motor and transmission shaft are set in parallel.
Aforesaid a kind of power semi-trailer battery-driven car chassis, wherein said storage battery is provided with two groups, and is arranged between front axle assy and the back axle assembly.
Aforesaid a kind of power semi-trailer battery-driven car chassis, wherein said control system is positioned at the back axle assembly rear.
The beneficial effect of the utility model: the power semi-trailer battery-driven car chassis medium power assembly of the utility model is designed to longitudinal U-shaped, and is positioned at postmedian position, chassis, so power transmission line is short, and it is also little to take longitudinal space.Can make cross member of frame complete like this, smooth in the middle of the frame assembly, reduce the vehicle frame upper level, vehicle frame rigidity and HOP ON property have all obtained guarantee like this.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
A kind of power semi-trailer battery-driven car chassis of present embodiment; Structure such as Fig. 1, shown in Figure 2; Mainly comprise frame assembly 1, front axle assy 2, back axle assembly 3, dynamic assembly, storage battery 6, control system 7; Motor 4c mouth is connected with the input end of transmission assembly 4b, and the mouth of transmission assembly 4b is connected with back axle assembly 3 input ends through transmission shaft 5, and dynamic assembly is set to semi-trailer dynamic assembly 4; Wherein semi-trailer dynamic assembly 4 is made up of motor 4c, transmission assembly 4b and " A " font propelling rod 4a; Be vertically " U " type setting, and be positioned at the place ahead of back axle assembly 3, semi-trailer dynamic assembly 4 one sides hang on the frame assembly 1; Opposite side hangs on the back axle assembly 3, forms the semi-trailer structure; Motor 4c and transmission shaft 5 are set in parallel, and storage battery 6 is provided with two groups, and are arranged between front axle assy 2 and the back axle assembly 3, and control system 7 is positioned at back axle assembly 3 rears.Can know by Fig. 1, Fig. 2; Semi-trailer dynamic assembly 4 is longitudinal U-shaped design; Be installed in back axle assembly 3 the place aheads, transmission assembly 4b also is so develops special change-speed box that change-speed box can be with after speed change, carry out 180 degree switching-over back outputs from motor 4c power; The input end of the mouth of transmission assembly 4b and back axle assembly 3 is connected transferring power through transmission shaft 5 and comes powered vehicle to advance.The utility model structure with original dynamic assembly by vehicle frame middle part vertically straight-though arrangement change the semi-trailer of existing postmedian in longitudinal U-shaped into and arrange; Compare with existing battery-driven car arrangement form; The vehicle frame good rigidity; The vehicle frame upper surface is smooth, and vehicle frame upper surface terrain clearance is little, characteristics such as power transmission efficiency height.
Although more than combine accompanying drawing that the preferred embodiment of the utility model is described, the utility model is not limited to the above-mentioned specific embodiment, and promptly all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
