Abstract
The utility model discloses a coach manual gearbox gear shifting power assisting device. A bidirectional air pump (4) is arranged on a manual gearbox (1), a follow-up air valve is integrated inside the bidirectional air pump (4), an air pipe (6) is connected onto an air inlet of a connecting rod at one end of the bidirectional air pump (4), the air pipe (6) is connected with an air storage barrel (7), a connecting rod at the other end of the bidirectional air pump (4) is connected with a gear moving-up arm (3), a control rod of the follow-up air valve penetrates into the connecting rod at the other end of the bidirectional air pump (4), the control rod is connected with one end of a control arm (5), and the other end of the control arm (5) is connected with a gear moving-up flexible shaft (2). Through mounting the gear shifting power assisting device on the manual gearbox, during a gear moving-up and shifting process when driving coaches, the gear shifting power assisting device provides efficient air assisting power, resolves problems that the coaches are difficult for moving up gears and heavy for shifting gears, reduces labor intensity of drivers, and then increases operation comfortableness during driving.
Description
Technical field
The utility model belongs to the bus technical field, specifically, relates in particular to the Manual transmission gear shift assistor of bus.
Background technology
Fast development along with China's public transport cause, the quantity of city bus is more and more, and these vehicles all are the Manual transmission of equipment basically, in the city bus operating condition, need frequent variable block, Manual transmission gearshift heavy weight drawback is more outstanding, and as adopting Automatic Transmission, the manufacturing cost of vehicle will significantly improve.Advance retaining difficulty gearshift heavy weight problem for solving Manual transmission,, advance retaining difficulty gearshift heavy weight problem and still can not access basic solution though in Manual transmission, installed synchro additional.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of passenger vehicle Manual transmission gear shift assistor that can light gearshift.
The technical solution of the utility model is as follows: a kind of passenger vehicle Manual transmission gear shift assistor, comprise Manual transmission, advance to keep off flexible axle and advance blocking arm, its key is: the two-way function air pump is housed on described Manual transmission, be integrated with the servo-actuated air valve in this two-way function air pump, be connected to tracheae on the admission port of described two-way function air pump one end link, this tracheae is connected with air receiver; Two-way function air pump other end connecting rod with advance blocking arm and be connected, and wear the control stalk of servo-actuated air valve in this end link of two-way function air pump, this control stalk is connected with an end of Control arm, the other end of described Control arm with advance to keep off flexible axle and be connected.
Adopt above technical scheme, at vehicle start, in service, when chaufeur was finished block selecting and need be advanced to keep off, when pilot control advanced to keep off flexible axle and draws forward, the pulling force that advances to keep off flexible axle at first acted on the Control arm of servo-actuated air valve, Control arm moves forward the switch of servo-actuated air valve by control stalk, thereby connect cylinder gas circuit behind the two-way function air pump, the pressurized air in the air receiver enters cylinder behind the two-way function air pump through tracheae, passes through piston rod, pulling is advanced blocking arm and is rotated counterclockwise, and finishes into retaining action.When pilot control advances to keep off flexible axle to pusher, the thrust of advancing to keep off flexible axle at first acts on the Control arm of servo-actuated air valve, Control arm moves the switch of servo-actuated air valve by control stalk backward, thereby connect the preceding cylinder gas circuit of two-way function air pump, pressurized air in the air receiver enters the preceding cylinder of two-way function air pump through tracheae, by piston rod, promote blocking arm and clockwise rotate, finish into retaining action.In advancing the retaining process, it is consistent that the force direction that advances to keep off flexible axle and the power-assisted direction of air pump remain, thereby realized the purpose of light gearshift.
As preferably, on the tracheae between described two-way function air pump and the air receiver, be in series with pressure regulating valve.
Beneficial effect: the utility model is by installing gear shift assistor on Manual transmission, advancing in retaining, the shift process when coaxial hybrid power passenger car in parallel is driven, actv. gas power-assisted is provided, solve this type of vehicle and advanced retaining difficulty gearshift heavy weight problem, alleviate the labour intensity of chaufeur, thereby improved the handling comfort of driving.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is Fig. 1 birds-eye view.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1 and Figure 2, the utility model by Manual transmission 1, advance to keep off flexible axle 2, advance blocking arm 3, two-way function air pump 4, servo-actuated air valve and component set-ups such as Control arm 5, tracheae 6, air receiver 7 and pressure regulating valve 8, wherein Manual transmission 1 is a prior art with advancing blocking arm 3, and its structure and assembly relation are not done at this and given unnecessary details.Pass through fixedly two-way function air pump 4 of mounting seat 9 on Manual transmission 1, be connected to tracheae 6 on the admission port of these two-way function air pump 4 one end links, these tracheae 6 series voltage-regulating valves 8 backs are connected with air receiver 7.Two-way function air pump 4 other end connecting rods with advance blocking arm 3 and be connected, wear the control stalk of servo-actuated air valve in two-way function air pump 4 these end links, the servo-actuated air valve is integrated in the two-way function air pump 4, the control stalk of servo-actuated air valve is connected with an end of Control arm 5, the other end of described Control arm 5 with advance to keep off flexible axle 2 and be connected, the keying of servo-actuated air valve, commutation are by advancing to keep off flexible axle 2 controls.
Principle of work of the present utility model is as follows:
At vehicle start, in service, when chaufeur is finished block selecting and need be advanced to keep off, when pilot control advances to keep off flexible axle 2 and draws forward, the pulling force that advances to keep off flexible axle 2 at first acts on the Control arm 5 of servo-actuated air valve, and Control arm 5 moves forward the switch of servo-actuated air valve by control stalk, thereby connects two-way function air pump 4 back cylinder gas circuits, pressurized air in the air receiver 7 enters two-way function air pump 4 back cylinders through pressure regulating valve 8, tracheae 6, by piston rod, pulling is advanced blocking arm 3 and is rotated counterclockwise, and finishes into retaining action.When pilot control advances to keep off flexible axle 2 to pusher, the thrust of advancing to keep off flexible axle 2 at first acts on the switch arm 5 of servo-actuated air valve, Control arm 5 moves the switch of servo-actuated air valve by control stalk backward, thereby connect two-way function air pump 4 preceding cylinder gas circuits, pressurized air in the air receiver 7 enters two-way function air pump 4 preceding cylinders through pressure regulating valve 8, tracheae 6, by piston rod, promote blocking arm 3 and clockwise rotate, finish into retaining action.
