Description

Gear selecting shift control mechanism based on car platform Multifunctional commerce car

Technical field

The utility model relates to gear selecting shift control mechanism, especially relates to a kind of gear selecting shift control mechanism based on car platform Multifunctional commerce car.

Background technique

At present CDV(is based on car platform Multifunctional commerce car) vehicle has the travelling comfort of car, the cargo capacity of micro-and the moulding of fashion concurrently with it, and the high visual field of sitting posture is good, oil consumption is low, configuration advantages of higher has entered common people family in a large number.The power assembly of this vehicle is divided into two classes at present: a kind of is domestic motor and speed changer, a kind of is motor and the speed changer of import, low but the combination property of domestic power assembly price comparison is not preponderated, the power assembly comprehensive comparison of import well but price comparison is high, in order to keep car load power character and economical index substantially constant and reduce costs, conventionally adopt and in the speed changer resource that producer can provide at home, selected all more approaching speed changers of a speed ratio and boundary conditions, reopen after shrinking away from theshell mould and can reach expected value with the Engine Matching of import and economical and power index, but the inner shifting structure of domestic speed changer and import speed changer be difference to some extent, its shifting pattern is 5-R-3-4-1-2, be difficult to meet the requirement of domestic user's use habit, if adjusting speed changer internal structure cost will raise, in order to reduce as much as possible development cost, can only redesign transmission control according to car load and existing domestic speed changer.

Summary of the invention

The utility model object is to overcome the deficiencies in the prior art, a kind of compact structure is provided, manufactures easy for installation, safe and reliable, manipulation good hand touch, can mate with existing domestic speed changer the gear selecting shift control mechanism based on car platform Multifunctional commerce car using.

For achieving the above object, the utility model can be taked following technical proposals:

Gear selecting shift control mechanism based on car platform Multifunctional commerce car described in the utility model, comprise base, block selecting rocking arm and shifting operation bar, one end of described shifting operation bar is provided with bulb, described bulb is arranged in base by being mated the upper and lower ball seat of use, the intermediate portion of described shifting rocking arm is hinged by block selecting axle and jump ring and the support arm that is connected on base, front end is hinged by block selecting village cover and the block selecting rocking arm bearing pin that is installed in bulb, and rear end is connected with block selecting bracing wire unit; Upper and lower ball seat surface peripheral at described bulb and that contact with described bulb is coated with acetal resin coating, is provided with elastic caoutchouc packing ring between described upper ball base and base.

On described support arm, be provided with stiffening rib, between the surface of contact of described bulb and upper and lower ball seat, be coated with lubricating grease.

That the utility model advantage is is simple in structure, compact, it is easy for installation to manufacture, usability is good, handle good hand touch, safe and reliable; By changing the position of the gear-shifting rocker arm strong point, shifting pattern is changed over to 1-2-3-4-5-R, can mate use with domestic retarder better; By applying one deck acetal resin coating on and upper lower ball base peripheral at bulb, reduce wear and avoid occurring excessive gap, reduce unloaded skid resistance, reduced the required precision of simple processing metal bulb and strengthen gearshift feel; By increase an elastic caoutchouc packing ring on upper ball base, utilize its resiliently deformable to make between lower ball base and bulb, to there is certain pretightening force, the size design precision that has simultaneously reduced upper lower ball base is beneficial to reduce its machining accuracy, saves cost and simplifies assembling.
