Description
Technical field
The utility model relates to a kind of retarder for pure electric vehicle, especially a kind of pure electric vehicle retarder with P shelves lockable mechanism and differential mechanism, belongs to the technical field of power transmission of pure electric vehicle propulsion system.
Background technique
The retarder that on market, existing pure electric vehicle uses, its basic structure composition is: be made up of casing, case lid, input shaft parts, intermediate shaft part, output shaft assembly.Wherein not yet have and be with differential mechanism and P shelves lockable mechanism simultaneously, therefore, need additional box of tricks and P shelves lockable mechanism during general common retarder entrucking, structure composition is complicated, and usability is poor.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, and provides a kind of structure simple, easy to install, the retarder for pure electric vehicle of good reliability.
The purpose of this utility model has been come by following technical solution, a kind of retarder for pure electric vehicle, it is primarily of casing, case lid, input shaft parts, intermediate shaft part, output shaft assembly forms, the input gear of described input shaft parts is fixed on input shaft, it engages with the jack shaft input gear of intermediate shaft part, the jack shaft output gear be coaxially connected with jack shaft input gear engages with the output gear of output block, the differential mechanism integrally combined with output gear is provided with in described output shaft assembly, the left and right two-semiaxle gear of described differential mechanism connects respective output shaft respectively, jack shaft in described intermediate shaft part is provided with a P and keeps off target wheel, and this P gear target wheel matches with the locking shifting block of P block locking mechanism, and carry out P gear locking after bonding.
Left and right two output shaft of the described input shaft of input shaft parts, the jack shaft of intermediate shaft part and output block is arranged on casing and case lid respectively by respective bearing; Described input shaft and motor pass through spline joint.
The utility model belongs to and improves the one of prior art, and it is simple that it has structure, easy to install, the features such as good reliability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1, a kind of retarder for pure electric vehicle described in the utility model, it is primarily of casing, case lid, input shaft parts 1, intermediate shaft part 2, output shaft assembly 3 forms, the input gear 11 of described input shaft parts 1 is fixed on input shaft 12, it engages with the jack shaft input gear 21 of intermediate shaft part 2, the jack shaft output gear 22 be coaxially connected with jack shaft input gear 21 engages with the output gear 31 of output block 3, the differential mechanism 4 integrally combined with output gear 31 is provided with in described output shaft assembly 3, the left and right two-semiaxle gear 41 of described differential mechanism 4 connects respective output shaft 42 respectively, jack shaft 23 in described intermediate shaft part 2 is provided with a P and keeps off target wheel 5, and this P gear target wheel 5 matches with the locking shifting block 6 of P block locking mechanism, and carry out P gear locking after bonding.
Shown in figure, left and right two output shaft 42 of the input shaft 12 of described input shaft parts 1, the jack shaft 23 of intermediate shaft part and output block is arranged on casing and case lid 7 respectively by respective bearing; Described input shaft 12 passes through spline joint with motor; Gear on input shaft and the engagement of jack shaft input gear, jack shaft input gear drives intermediate shaft part to rotate, jack shaft output gear engages with the output gear on differential mechanism, output gear drives differential mechanism rotating, and the differential gear in differential components drives output shaft assembly to rotate Driving Torque.When vehicle is in P shelves, locking shifting block and the P shelves target be contained on intermediate shaft part of P shelves lockable mechanism are taken turns and are combined, and realize P shelves latch functions.
Embodiment: shown in Fig. 1, input shaft parts 1, intermediate shaft part 2, differential mechanism 4 are bearing on casing and case lid 7 by bearing, input shaft 12 and motor pass through spline joint, input gear 11 on input shaft 12 and jack shaft input gear 21 engage, jack shaft input gear 21 drives intermediate shaft part 2 to rotate, jack shaft output gear 22 engages with the output gear 31 on differential mechanism 4, output gear 31 drives differential mechanism 4 to rotate, and the differential gear 41 in differential mechanism 4 drives the output shaft 42 of output shaft assembly 3 to rotate Driving Torque.When vehicle is in P shelves, the locking shifting block 6 of P shelves lockable mechanism be contained in the P shelves target on intermediate shaft part 2 and take turns 5 and be combined, realize P shelves latch functions.
