Abstract
The utility model relates to a steering column assembly for vehicle steering, in particular to a structure which can improve rigidity of a steering column for the steering column assembly telescopically adjustable. The structure is characterized in that a clamping portion (4a) is integrally formed on an outer lateral column (4) by means of casting, and an inner lateral column (3) is retained through the clamping portion (4a).
Description
Technical field
The utility model relates to the Steering gear assembly using in the steering hardware of using at trailer reversing, relates in particular to the Steering gear assembly that can adjust the axial length of steering shaft, can stretch and adjust.
Background technology
In the past, fastening by fastening device, and make to be located at claw on interior week of mixed lateral column and the periphery butt of columnae medialis, mixed lateral column and columnae medialis are remained on the position of regulation, and by the releasing of fastening device, adjust the axial relative position of steering shaft between mixed lateral column and columnae medialis.
Patent documentation 1: TOHKEMY H11-278283 communique
But, there is following problem: because mixed lateral column and columnae medialis are kept by claw, so as the rigidity step-down of the Steering gear assembly being formed by mixed lateral column and columnae medialis.
Utility model content
Therefore, described in technical scheme 1, the utility model is a kind of Steering gear assembly, it is consisted of the mixed lateral column that a side's of steering shaft end is rotated to the columnae medialis of supporting freely and the opposing party's of described steering shaft end rotation is supported freely, described columnae medialis and described mixed lateral column are chimeric freely along endwisely slipping of described steering shaft, it is characterized in that, described mixed lateral column has: holding part, and this holding part forms and has the maintenance face of the described columnae medialis of maintenance with described mixed lateral column by casting; And fastening device, this fastening device is fastening described holding part in order to keep described columnae medialis, by the fastening releasing of described fastening device, can adjust the axial relative position of described steering shaft between described mixed lateral column and described columnae medialis, the part in the interior week of at least holding part of described mixed lateral column has been implemented fine limit work.According to the utility model, because the holding part by being formed on mixed lateral column keeps columnae medialis, so uprise as the rigidity of Steering gear assembly.Be preferably, Steering gear assembly is characterised in that, can also adjust the angle of steering shaft by the releasing of described fastening device.
Accompanying drawing explanation
Fig. 1 represents Steering gear assembly of the present utility model.
The upper surface of Fig. 2 presentation graphs 1.
Fig. 3 represents the structure in the interior week of mixed lateral column and mixed lateral column.
The specific embodiment
As shown in Figure 1 and Figure 2, Steering gear assembly of the present utility model makes mixed lateral column 4 and columnae medialis 3 can be along chimeric under the state in axial sliding of steering shaft 1.End (accompanying drawing right side) a side of mixed lateral column 4 is upper, has formed holding part 4a with mixed lateral column 4.Mixed lateral column 4 and holding part 4a in the mode with the relative 12a of portion, 12b by casting integrated formation.Be preferably, mixed lateral column 4 is formed by light alloy materials such as aluminum alloys.In addition, as shown in Figure 1 and Figure 2, Steering gear assembly of the present utility model has fastening device, and this fastening device consists of binding bolt 13, clamp nut 14, locking locknut 15, bar 16, the first cam part 17 and the second cam part 18.By the fastening of fastening device or releasing, the relative axial position between mixed lateral column 4 and columnae medialis 3 can be kept or be adjusted to assigned position.And, on graphic mixed lateral column 4, be also formed with inclination bolt maintaining part 8.In addition, the handle-bar for driver's operation is installed on the 1a of the end of steering shaft 1, on the opposing party's end plate 2, steering gear mechanism is installed.Groove 5, support 6(6a for tilt adjustments), support 7, inclination bolt maintaining part 8, distance piece 9, inclination center pin 10, gap 11 and capsule slide block 19(19a, 19b) (capsule) for Steering gear assembly is installed to vehicle body in the mode of regulation.Ball-bearing casing 31,33 rotations keep steering shaft 1 freely.The axial position of back-up ring 35,37 restriction steering shafts 1, stopper bolt 43 cooperates to limit the adjustment of the relative position between mixed lateral column 4 and columnae medialis 3 with axial groove 3b.
As shown in Figure 3, in the present embodiment, the interior week of mixed lateral column is divided into L0～L3 vertically according to the difference of its internal diameter size.At this, preferably the pass of internal diameter size is D2≤D3≤D1 < D0.In addition, preferably, at least as the inner peripheral surface within the scope of the L2 of the interior circumferential portion of holding part 4, be implemented as accurately machined lapped finish, so that internal diameter size is D2.The part of having implemented lapped finish not only dimensional accuracy is improved, and roughness of surface, circularity are also improved, thus, and the contact condition between the periphery of columnae medialis 3 improves, can stably keep columnae medialis 3, thus, make to improve as the rigidity of Steering gear assembly.In addition, in this case, the roughness of the face that implemented the roughness of surface of the part of lapped finish, in other words contacts in order to keep columnae medialis 3 with the outer peripheral face of columnae medialis 3 is preferably below 25 μ mRa.But, from cost-benefit viewpoint, not preferred lower than the roughness of 0.01 μ mRa.
In addition, as fine limit work, be not limited to above-mentioned lapped finish, and, implement accurately machined position and be not limited to above-mentioned position, can be separately or apply in combination shot-peening processing, extrusion process (burnishing-in), scratch brushing processing, honing processing etc.
Claims (2)
1. a Steering gear assembly, it consists of the mixed lateral column that a side's of steering shaft end is rotated to the columnae medialis of supporting freely and the opposing party's of described steering shaft end rotation is supported freely, described columnae medialis and described mixed lateral column are chimeric freely along endwisely slipping of described steering shaft, it is characterized in that
Described mixed lateral column has: holding part, and this holding part forms and has the maintenance face of the described columnae medialis of maintenance with described mixed lateral column by casting; And fastening device, in order to keep described columnae medialis, fastening described holding part, by the fastening releasing of described fastening device, can be adjusted the axial relative position of described steering shaft between described mixed lateral column and described columnae medialis to this fastening device,
The part in the interior week of at least holding part of described mixed lateral column has been implemented fine limit work.
2. Steering gear assembly according to claim 1, is characterized in that, can also adjust the angle of steering shaft by the releasing of described fastening device.
