Description
Technical field
The present invention relates to equation motorcycle race mechanism more particularly to it is a kind of apply on equation motorcycle race by adjusting gear
Position adjusts device so as to adjust inter-lobe clearance.
Background technique
Chinese college students formula car contest (referred to as " Chinese FSC ") is one by institution of higher learning's automobile engineering or automobile
Relevant speciality students form a team participate in Automobile Design and Manufacturing match.Each competition fleet manufactures according to race rule and racing car
Standard, designed, designed has outstanding representation with producing one in terms of acceleration, braking in year
Small lift's seat leisure racing car, can successfully complete the match of all or part of race link.University student's equation motorcycle race to turn
Requirement to system: 1, steering system must can at least act on two wheels.2, steering system must install effective turn
To limited block, (four-bar mechanism inverts at a node) is inverted to link mechanism to prevent rotation stop.Limited block it is mountable
It turns on column or rack gear, and must be prevented from tire and contact suspension, vehicle body or frame part in Turning travel.3, steering system
The free travel of system must not exceed 7 degree (measuring on the steering wheel).4, allow using rear-axle steering, but its steering angle must be mechanical
Limit from front ± 3 degree (measuring).5, steering wheel must be mechanically connected with front-wheel.It is forbidden to use steering-by-wire.6, direction
Disk is necessarily mounted on device for quick-dismantling, it is necessary to assure driver is in normal driving sitting posture and while wearing gloves can operate device for quick-dismantling.7,
Steering wheel profile is necessary for the subcircular being continuously closed or nearly ellipse.Such as: the outer profile of steering wheel can have some parts
Tend to straight line, but there cannot be the part of indent.It is forbidden to use H-shaped, 8 types or split steering wheel.
Current equation motorcycle race field has racing track feature complicated and changeable, the steering meeting of driver's high frequency in motion
The connecting rod rocker arm body or gear and rack teeth mechanism of steering are caused to wear, lead to the free travel of steering system in use
It becomes larger possibly even beyond 7 degree (measuring on the steering wheel), to violate the 3rd of the big tournament rules of Chinese college students equation
Regulations.And the excessive driver of free travel of steering system can obviously feel to turn to lag, generate security risk.And it is turned in high frequency
During, wheel and rack is more easy to wear, so guaranteeing that reasonable inter-lobe clearance is the key that reduce free travel.
And the existing pinion-and-rack steering engine inter-lobe clearance applied on equation motorcycle race adjusts device, mostly in rack gear and
Rack support seat is arranged in pinion gear engagement place, and helical spring is arranged in the support base back side, is arranged in the other end of helical spring and adjusts
Plug screw, by adjusting plug screw adjusting tooth rack-and-pinion back lash.This pinion-and-rack steering engine inter-lobe clearance adjusts device
Have the following problems: when vehicle driving is on uneven road surface, tire can bring rack gear biggish impact, it is this impact by
Rack gear passes to support base, and therefore support base can tilt moves back and the collision of turning machine shell or friction partially, thus bring collision
Or the one side that rubs partially can aggravate related components abrasion and reduce the service life, and on the other hand can generate abnormal sound and driver is driven
Anxiety is sailed, driver comfort is influenced.And when abrasion loss is larger, due to needing to eliminate inter-lobe clearance, support base axial displacement compared with
Greatly, cause rack type variable larger, rack gear receives alternating load, is also easy to produce failure；And steering resistence is larger.
