In recent years, energy-conserving and environment-protective are more and more subject to people's attention, and the electronic class new forms of energy buses such as pure battery electric bus, hybrid-power bus, extended-range bus, double source trackless electric bus, trackless electric bus develop rapidly because of the advantage with energy-saving and emission-reduction.The scheme that existing electronic class new forms of energy bus generally adopts single propons to turn to, tyre load is large, in order to meet carrying demand, need to use the tire of larger volume, this just causes the car tank top plate height of steering tire installation site higher, in railway carriage, the seat arrangements at steering tire place is higher, is not easy to occupant and takes a seat and stand up.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of simple in structure, be convenient to the doube bridge steering hardware of electric bus realized, when its application, can reduce the impact on seat arrangements in railway carriage.
The present invention addresses the above problem and is achieved through the following technical solutions: the doube bridge steering hardware of electric bus, comprise the first steeraxle, the second steeraxle, longitudinal tie, steering booster and centre link, described the first steeraxle and the equal horizontally set of the second steeraxle and parallel to each other, on the first steeraxle and the second steeraxle, be all connected with pitman arm, described longitudinal tie and centre link all longitudinally arrange and coaxially arrange, described longitudinal tie two ends connect respectively the pitman arm on steering booster and the first steeraxle, centre link two ends connect respectively the pitman arm on pitman arm and the second steeraxle on the first steeraxle.When the present invention applies, be installed on the chassis of the electronic class new forms of energy buses such as pure battery electric bus, hybrid-power bus, extended-range bus, double source trackless electric bus, trackless electric bus, steering booster reaches power by vertical position bar the pitman arm connecting on the first steeraxle, and under the drive of centre link, reach the pitman arm of the second steeraxle, under the induced effect of pitman arm, the first steeraxle and the second steeraxle rotate by ackerman angle separately, realize doube bridge and turn to.
Further, described pitman arm comprises the cross connecting plate of horizontally set and the longitudinal connecting panel longitudinally arranging, described longitudinal connecting panel front end is connected with cross connecting plate, described pitman arm is by being arranged on the first steeraxle or the second steeraxle through cross connecting plate and the locating dowel pin of longitudinal connecting panel connecting portion, pitman arm is flexibly connected with the first steeraxle or the second steeraxle by its longitudinal connecting panel rear end, and described longitudinal tie is connected with pitman arm with centre link is all the connected longitudinal connecting panel end relatively other end by being connected to cross connecting plate.When pitman arm of the present invention is movable, it can rotate around locating dowel pin.
In order to ensure the structural strength of pitman arm, further, the cross connecting plate of described pitman arm and longitudinally connecting panel become one.
Further, described the first steeraxle and the second steeraxle both sides are provided with steered wheel.
In sum, the present invention has following beneficial effect: the present invention includes the first steeraxle, the second steeraxle, longitudinal tie, steering booster and centre link, wherein, on the first steeraxle and the second steeraxle, be all connected with pitman arm, longitudinal tie two ends connect respectively the pitman arm on steering booster and the first steeraxle, centre link two ends connect respectively the pitman arm on pitman arm and the second steeraxle on the first steeraxle, the present invention adopts said structure, integral structure is simple, be convenient to realize, when the present invention is applied on electronic class new forms of energy bus, steering power acts on the first steeraxle and the second steeraxle simultaneously, the mode that adopts doube bridge to turn to, the load that each tire bears reduces, and then can reduce the volume of tire, can reduce the seat arrangements height at steering tire place in railway carriage, so, steering tire installation site reduces the impact of seat arrangements in railway carriage, be convenient to seat reasonable Arrangement in railway carriage, so that occupant takes a seat and stands up, especially old, a little less than, sick, the upper and lower seat of residual personage is more convenient.
