歯車に係脱させている。A conventional toggle type parking device consists of a toggle mechanism that pivots its teeth to engage and disengage freely from the parking gear, and an idle mechanism that drives the toggle mechanism. 1. A ball having one end pivotally connected by a fixed pin, extending substantially tangentially to the outer periphery of the parking gear from the pivot point, and having teeth on the side surface that can be freely engaged and detached from the parking gear by pivoting movement; A toggle bar having one end connected to the other end of the ball via a parallel first movable pin, and a toggle bar having one end connected to the toggle bar via a second movable pin parallel to the southeast axis. pivotally mounted on the other end and said tooth moon 1.1
When the swing arm whose other end is fixed to the case by a second fixed pin parallel to 111, the first movable pin, the second movable pin, and the second fixed pin are arranged in a substantially straight line. The idle mechanism is formed on the edge iNB of the toggle lever opposite to the ball. By fully rotating the engagement pin that engages with the notch, the tooth of the ball i1 is engaged with and disengaged from the parking gear.

を特徴とする。However, in conventional parking devices, 5-pole ffi
Since the stroke of the engaging pin that reciprocates between the R and P ranges is relatively long, the size of the parking device increases as the stroke reciprocates between the R and P ranges.Therefore, the object of the present invention is to: The purpose of the present invention is to enable the ball teeth to engage and disengage from the parking gear with a small stroke of the engagement pin.1 The present invention has the above-mentioned type of toggle tie. It is characterized by having an irradiated surface that approaches the pin axis as it moves along with the tip.

装置全体の寸法全コンパクトにできる。According to the above configuration of the present invention, when the ball tooth and the parking gear engage with each other with respect to the P position of the manual lever, the notch of the toggle lever is located far from the tip of the engagement pin, that is, apart from the axis. When the ball j tooth and the parking gear are furthest apart from each other corresponding to the R position of the manual lever, the notch of the toggle lever is located at the part closest to the tip of the retaining pin, i.e. the shaft. Due to the abutment of the sliding surface closest to the center, a longer stroke of the toggle lever or ball is obtained with the same pivot angle of the engagement pin compared to conventional parking devices. Therefore, the entire size of the idle mechanism, that is, the parking device can be made compact.

The ball 27 engages, and the position of the parking position of the manual/<-1875: V due to the swinging is fixed.
The first idler lever 21 swings via the pin 20, and the second idler lever 21 swings via the tone force 1 knock 25 (-24 force; swinging force is applied, and the engagement pin 15 force of several orders of magnitude is applied to its tip = Fig. 1). The ball 2 is moved from the chain line position to the solid line position 5, thereby pressing the protrusion 12C' of the toggle lever 12 to move the toggle lever 12 to the full solid line position. Place IW on the first turtle, and anastomose its tooth 2a' to the tooth 1a of the parking gear 1.
It can be flushed. m2a is 1.-the biasing force of the John spring 25, the fixing pin 11 located on a straight line, the first. Due to the action of the toggle mechanism 13 of the second movable bins 8, 10: solid line position 1
Fixed at Δ 11, the rotation of the parking gear 1 is fixed.

かれる。The case where parking is released from the state shown by the solid line in FIG. 1 will be explained. First, when the shift 1/bar (not shown) is operated from the parking position to the R (release) position, the manual lever 18 swings through the lever 16 and manual shaft 17', and the ball 27 of the detent mechanism 26 is released from the P range. The parking position of the manual valve is unlocked.

トにできる。As mentioned above, the engagement pin 15 pivots between the solid line (iZ position and the vertical line position) in FIGS. 1 and 2 in correspondence with the P and R positions of the shift I lever. engagement pin 15
The relationship between this and the protrusion 12c of the toggle lever 12 is shown in detail in FIG. As is clear from this figure, the idler shaft 2312c of the engagement pin 15 slides on the side surface of the engagement pin. That is, when the shift lever is in the P position, the protruding portion 12c still contacts the base portion 15b of the engagement pin 15, and when the shift lever is in the R position, the protruding portion 12c contacts the tip portion 15a,
During this period, it substantially contacts the tapered surface of the intermediate portion 15c. The stroke amount 12 (FIG. 7) of the protrusion 12c corresponds to the pivot angle θ of the engagement pin 15 of the present parking device, and the protrusion 120 corresponds to the pivot angle θ of the retaining pin 15' of the conventional parking device. It is clear that the stroke amount of this parking device is longer than the stroke amount of the parking device of the present invention. To obtain the same stroke amount 11 as the conventional parking device, i/i: means that the pivot angle of the engagement pin 15 may be smaller than the current pivot angle θ. The entire dimension of the mechanism 14 can be made compact, and as a result, the entire structure of the parking device can also be made compact.

特徴とするパーキング装置。[Scope of Claims] One end is pivoted by a first fixed pin (i'L) substantially parallel to the axle of the parking gear, and extends from the pivot point approximately tangentially to the outer circumference of the parking gear. a toggle lever having one end connected to the other end of the ball via a first movable pin parallel to the gear axis; and a second movable lever parallel to the gear axis. a swing arm whose one end is pivotally connected to the other end of the toggle lever via a pin and whose other end is fixed to the transmission case by a second fixing pin parallel to the gear axis; and the first movable pin; A toggle consisting of a 1.-sition sublinog that disengages the ball teeth and the parking gear h times, which is achieved when the second movable pin and the second fixed pin are arranged substantially in a straight line. By rotating the mechanism and an engaging pin that engages with a notch formed in an edge opposite to the ball of the toggle lens, the toggle mechanism is toggled and the ball tooth is moved to the parking gear. In a parking device comprising an idle mechanism that engages and disengages the vehicle. 9.5. The notch of the toggle lever asymptotically approaches the pin axis as it moves around the sliding surface of the sliding engagement pin of the idle mechanism toward the tip. A parking device characterized by having = on its face.
