The two-gear variable-speed driving device comprises a driven shaft (1), a gear reversing mechanism and a gear reversing operation mechanism, wherein an isolator (2) is arranged on the driven shaft (1), a first-gear driven gear (10) is arranged on the isolator (2), the gear reversing operation mechanism is connected with the gear reversing mechanism, and the gear reversing mechanism is arranged on the driven shaft (1) and corresponds to the first-gear driven gear (10). The two-gear variable-speed driving device of the electric vehicle has the advantages of ingenious structural design and convenience in manufacture and mounting and is flexible and reliable for gear shift, stable in power switching, free of impact or pause, high in reliability and higher in safety and has the backup capability so as to facilitate drivers.
Description
Technical field
The utility model relates to a kind of driving device for electric vehicle, particularly a kind of battery-driven car two gear speed-changing driving devices.
Background technology
At present, in order to solve existing battery-driven car when the variable block, must reduce the speed of a motor vehicle or interrupt the problem that power just can carry out variable block, many producers have adopted friction clutch to solve this problem, the patent of invention that a kind of name is called " a kind of battery-driven car two gear speed-changing driving devices " is disclosed in CN102642595A, it comprises electrical motor, Power train and diff, it also comprises friction clutch, described electrical motor is connected with diff with friction clutch respectively by Power train, is provided with isolator at described Power train.The problems referred to above that mechanism has although it is so occurred when having solved variable block, still, this battery-driven car two gear speed-changing driving devices lack the function of reversing gear, can't so that battery-driven car move backward.
The utility model content
The purpose of this utility model just provides a kind of battery-driven car two gear speed-changing driving devices with gear reversing function.
The purpose of this utility model is to realize by such technical scheme, a kind of battery-driven car two gear speed-changing driving devices, comprise driven shaft, be provided with isolator at driven shaft, be provided with a gear driven gear at isolator, it also comprises reverse gear mechanism and the reverse-gear operating mechanism that is connected with reverse gear mechanism, and described reverse gear mechanism is arranged on the driven shaft, and corresponding with a gear driven gear.
Wherein, described reverse gear mechanism comprise can with the clutch ratchet of the contrite gear engagement of a gear driven gear, be provided with spring between isolator and clutch ratchet at described driven shaft, in clutch ratchet arranged outside the back-up ring that is positioned on the driven shaft is arranged; Described reverse-gear operating mechanism comprises declutch shift shaft, shift fork control arm and torque arm, be provided with the shift fork that can slide at declutch shift shaft at declutch shift shaft, one end of described shift fork is stuck in the circular groove on the clutch ratchet, and the other end is connected with torque arm by being connected on the shift fork control arm.
Owing to having adopted technique scheme, the utlity model has the advantage that structure design is ingenious, manufacturing is easy for installation, adopt it not only can be so that the variable block flexibility and reliability, powershift is steady, without impacting or pausing, reliability is high, has improved safety performance, and have the ability of reversing, made things convenient for the driver.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail; but the utility model is not limited to these embodiments; any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of battery-driven car two gear speed-changing driving devices, comprise driven shaft 1, be provided with isolator 2 at driven shaft 1, be provided with a gear driven gear 10 at isolator 2, it also comprises reverse gear mechanism and the reverse-gear operating mechanism that is connected with reverse gear mechanism, and described reverse gear mechanism is arranged on the driven shaft 1, and corresponding with a gear driven gear 10.
Wherein, reverse gear mechanism comprises the clutch ratchet 3 that can mesh with the contrite gear of a gear driven gear 10 in the utility model, be provided with spring 4 between isolator 2 and clutch ratchet 3 at described driven shaft 1, the back-up ring 5 that is positioned on the driven shaft 1 is arranged in clutch ratchet 3 arranged outside; Reverse-gear operating mechanism comprises declutch shift shaft 6, shift fork control arm 7 and torque arm 9, being provided with at declutch shift shaft 6 can be at the shift fork 8 of declutch shift shaft 6 slips, one end of described shift fork 8 is stuck in the circular groove on the clutch ratchet 3, and the other end is connected with torque arm by being connected on the shift fork control arm 7.
The utility model is like this work: when needs carry out car backing operation with battery-driven car, after car load stops, first speed-changing mechanism is placed a gear, spur torque arm 9 again, torque arm 9 is rotated and is driven 7 rotations of shift fork control arm, shift fork control arm 7 promotes shift fork 8 and slides at declutch shift shaft 6 when rotating, shift fork 8 promotes the contrite gear engagement of clutch ratchet 3 and a gear driven gear 10 when sliding, and Compress Spring 4, and this is that system is in the gear that reverses gear, then astern operation is carried out in actuating motor 11 counter-rotatings; After reversing is finished, unclamp torque arm 9, spring 4 promotes clutch ratchet 3 and separates with a contrite gear that keeps off driven gear 10 under the effect of elastic force, returns to again a gear state.
