The utility model content
The purpose of this utility model just provides a kind of two stage speed change of realizing, can adapt to the afterburning speed change back axle of battery-driven car of different road surfaces power needs.
The purpose of this utility model is to realize by such technical scheme, comprise the inner rotary member that is arranged in the rear axle housing body, inner rotary member is provided with and inner rotary member bonded assembly output gear, described inner rotary member is connected with semiaxis by the semiaxis tooth, it is characterized in that back axle is provided with and electrical motor bonded assembly speed-changing mechanism, and with speed-changing mechanism bonded assembly selector device.
Above-mentioned speed-changing mechanism comprises the variable gear casing, parallelly in the variable gear casing be provided with input shaft and the axle of passing a bridge, above-mentioned input shaft one end passes casing, the above-mentioned input shaft other end by bearing fixing in casing, input shaft is provided with quickly tooth, baulk ring tooth and driving tooth at a slow speed, the baulk ring tooth is at tooth quickly with at a slow speed between the driving tooth, above-mentioned tooth quickly and at a slow speed driving tooth respectively be arranged on the axle of passing a bridge with output gear ingear driven tooth and the engagement of gap bridge tooth, above-mentioned gap bridge axle by bearing fixing in casing; Above-mentioned selector device comprises the shift fork that is stuck on the baulk ring tooth, above-mentioned shift fork successively by declutch shift shaft and soft drawn rope be arranged on the bar handle of handling on the seat and be connected; The variable gear casing is connected with rear axle housing body by screw.
The utility model is like this work: an end that the turning cylinder and the input shaft of motor is passed casing is connected, after electrical motor rotates, driving the baulk ring tooth by input shaft rotates, when needs are run at high speed, the pulling bar handle is stirred shift fork, by stirring of shift fork with baulk ring tooth and gear mesh quickly, the rotation of baulk ring tooth has driven quickly, and gear rotates, the rotation of gear quickly drives output gear by driven tooth and rotates, the rotation of output gear is delivered on the semiaxis by the semiaxis tooth, runs at high speed thereby promote battery-driven car; When needs carry out low speed driving, the pulling bar handle is stirred shift fork, by stirring of shift fork with baulk ring tooth and driving tooth engagement at a slow speed, the rotation of baulk ring tooth drives at a slow speed, and driving tooth rotates, driving tooth rotates by the moving axle of passing a bridge of gap bridge cingulum at a slow speed, the rotation of gap bridge axle has driven the output gear rotation, and the rotation of output gear is delivered on the semiaxis by the semiaxis tooth, thereby promotes the battery-driven car low speed driving.
Produce for convenience, reduce the manufacturing cost of gear, above-mentioned tooth quickly, baulk ring tooth, driving tooth, gap bridge tooth, driven tooth and output gear are cylindrical wheel at a slow speed.
Owing to adopted technique scheme, the utlity model has manufacturing, easy to assembly, effectively reduce the advantage of motor power (output) loss, also it can give full play to the power of electrical motor under different road conditions conditions in use.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Embodiment: as shown in Figure 1, the afterburning speed change back axle of a kind of battery-driven car, comprise the inner rotary member 15 that is arranged in the rear axle housing body 18, inner rotary member 15 is provided with and inner rotary member 15 bonded assembly output gears 12, inner rotary member 15 is connected with semiaxis 17 by semiaxis tooth 13, back axle is provided with and electrical motor bonded assembly speed-changing mechanism, and with speed-changing mechanism bonded assembly selector device.
Speed-changing mechanism comprises variable gear casing 21, parallelly in variable gear casing 21 be provided with input shaft 9 and the axle 11 of passing a bridge, input shaft 9 one ends pass casing 21, input shaft 9 by bearing fixing in casing 21, input shaft 9 is provided with quickly tooth 8, baulk ring tooth 7 and driving tooth 20 at a slow speed, baulk ring tooth 7 is at tooth 8 quickly with at a slow speed between the driving tooth 20, quickly tooth 8 and at a slow speed driving tooth 20 respectively with the driven tooth 10 and 19 engagements of gap bridge tooth that are arranged on the axle 11 of passing a bridge, the axle 11 of passing a bridge by bearing fixing in casing 21; Selector device comprises the shift fork 6 that is stuck on the baulk ring tooth 7, shift fork 6 successively by declutch shift shaft 4 and soft drawn rope 2 be arranged on the bar handle of handling on the seat 13 and be connected; Variable gear casing 21 is connected with rear axle housing body 18 by screw; Output gear 12 and driven tooth 10 engagements.Quickly tooth 8, baulk ring tooth 7, driving tooth 20, gap bridge tooth 19, driven tooth 10 and output gear 12 are cylindrical wheel at a slow speed.
